Pre-dispersed R-80 is one of the components from the composition of the Resorcinol,formaldehyde and white carbon black.It will form the Resorcinol-formaldehyde-resin system by the adhesion from rubber and fabric or all-steel cord which produced by the mixed together with formaldehyde offer(such as HEXA-80 or RA-65) during producing.This system is suitable for rubber and stiffener,such as the adhesion between fiber/glass fiber and metal(such as all-steel cord)

Process:

Generally, thin crystals resorcinol tends to bond with equipment and hard to disperse during mixing process.Pre-dispersed R-80 can solve this problem.
